mAb against membrane-bound TNFa

Dear Flowers,


I have been looking for mAb directed against human membrane-bound form of TNFa, preferentialy conjugated to PE or dyes emitting red fluorescence (488 or 635 nm excited). I have found only one manufactured by R&D but FITC conjugated. 
Any advice would be highly appreciated.
